Obstacle

A dirt wall in Pikmin 3, an obstacle that blocks a path until it has been destroyed.

To do: Check if Pikmin contribute to a task in a linear fashion or logarithmic fashion. i.e. do 50 Pikmin take exactly twice as long to take down a gate as 100, or are they faster? Check other obstacles too, and check all games.
Care to do so?

Obstacles are interactive objects that stand in the way of Pikmin and leaders. Some obstacles can be destroyed by having Pikmin attack them, some can be overcome through the use of tools, and some cannot be destroyed at all and must be worked around. With creative use, some of these obstacles can end up helping the player in unique ways when they are cleared, like a cardboard box initially being pushed to get out of the way, but also ending up next to a ramp to serve as a makeshift bridge. In this sense, some obstacles can partially serve as tools in and of themselves.

Minor obstacles

Several other kinds of obstacles appear in the Pikmin series, but are much rarer than the obstacles listed above.

Trivia

In Pikmin 2, Pikmin that are attacking an obstacle while latched on will cause damage at a faster pace than those that are standing on the ground.^[1] This can be achieved with bridges by pushing the Pikmin off to the side and letting it go back to the bridge on its own, where it should hopefully cling on instead.
